Network (Network settings)
This printer supports TCP/IP and TCP/IP (IPv6) protocols.
IP is an abbreviation for Internet Protocol. This printer routinely uses the TCP/IP (IPv4) protocol, but provides a separate
setting for the next-generation IP, IPv6.
TCP/IP (IPv4) uses 32-bit IP addresses, but the rapid growth in the number of Internet users has resulted in a shortage of
IP addresses. IPv6 was developed to expand the range of available IP addresses by using 128-bit IP addresses.
The options available in the Network settings are as follows:
• TCP/IP (Enable/Disable TCP/IP)...4-57
• IPv4 Setting (TCP/IP IPv4 settings)...4-58
• IPv6 Setting (TCP/IP IPv6 settings)...4-61
• Protocol Detail (Detailed settings for the network protocol)...4-63
• Restart Network (Restarting the network card)...4-64

TCP/IP (Enable/Disable TCP/IP)
The TCP/IP system refers to the Internet system, which has a 5-layer structure consisting of the interface layer, link layer,
network (IP) layer, transport (TCP/UDP) layer and application layer.
The interface layer is a key layer in the TCP/IP system that provides an abstracted interface that is not dependent on the
link (communication line: frame relay or Ethernet, etc.) to the IP module (IP layer). This means that the IP module can use
this abstracted interface (which is not dependent on the link type) to exchange IP packets back and forth with the link layer.

Note
Check with your network administrator when selecting the network setting. After all network related settings
have been done, restart the network. Refer to Restart Network (Restarting the network card) on page 4-64. This is
mandatory to make the settings effective!
When Command Center RX is used, network parameters and security settings can be conveniently changed and
checked from your PC. For more information, refer to the Command Center RX User Guide.
